Where do I ad DUPLICATE ENTRY UPDATE?

[glamorize]

Can someone please inform me where do I ad " INSERT INTO table (a,b,c) VALUES (1,2,3)
ON DUPLICATE KEY UPDATE id=LAST_INSERT_ID(id), c=3;
"

I am trying to have it set up that if the records exsists already it will just update the info in mysql.

$insert = "INSERT INTO almclmb8 (contact_name, email, login, passw, time, contact_phone)
VALUES ('".$name."','".$email."','".$login."','".$password."','".$time."','".$phone."')";


$result = mysql_query($insert) or die(mysql_error()); 


    mysql_query($query);
if (!$result) {
    $message  = 'Invalid query: ' . mysql_error() . "\n";
    $message .= 'Whole query: ' . $query;
    die($message);
}

echo $query; 
"('','{$contact_name}','{$email}','{$login}','{$passw}','{$time}','{$contact_phone}')"; 


// Perform Query
$result = mysql_query($query);


?>

Just add the "ON DUPLICATE KEY UPDATE ...." at the end of the $insert string.

Why would you want to be modifying the id column? You could screw up your entire database with messing with the auto_increment field....
